Chapter 6: Analysis of longitudinal data
Implement the analyses of Chapter 8 of MABS using RATS data
1 Preparation
1.1 Read the dataset
#read the wide format dataset
rats <- read.csv("data/rats.csv")#I prefer lower case object name for typing # convenience
#read the long format dataset
ratsl <- read.csv("data/ratsl.csv")#"l" is for long format
#delete the redundant X variable, which are the row names.
rats <- rats[-1]
ratsl <- ratsl[-1]1.2 Factor the categorical variables
R does not recognize categorical variables automatically as factors. I will do manually that here.

dplyr::select(ID, group, time, weight) #recorder the variables1.3 Check the wide format dataset
In longitudinal study, data are usually analyzed in wide format, so that variables carrying same indicators for different clusters (e.g. time points) could enter model as one parameter. To distinguish values from different clusters, another variable is generated for labeling the identity of clusters. For the reason, I will only analyze the long format dataset and check if the frame corresponds to the above-mentioned idea.

## data frame with 0 columns and 176 rowsAccording to the checks above，there are one by-individual identifier “ID”, which is a factor; two by-cluster identifier “group” and “time”, which are factor and numeric, respectively; one by-observation measure “weight”, which is numeric. The frequency table reveals that there are 16 individual rats, each has 11 repeated measures, resulting in 176 (16×11) unique observations; the rats can be clustered into 3 treatment groups, with a sample of 8, 4 and 4, respectively; or they can be clustered into 11 times points, and at each point every rat’s weight was measured and recorded into variable “weight”. According to the descriptive statistics for weight, the rats, irrespective of individual and time effects, have a weight of 384.5±127.2 grams. No missing values is present in the data.
1.4 Determine sensible model for the data
1.4.1 Hypothesis
In the data, the variable I am interested in is “weight”. The reasons are a. it is a numeric variable and hence carries more information than factors; b. it is the only variable that varies across all the observations; c. Digging into how types of nutritional diet would influence weight has substantial practical meaning in health and nutritional science.
Now that I have chosen a numeric variable “weight” as the dependent variable, linear model is definitely one of the preferred choices for modeling. But before a decision, I should check if there is any potential linear relationship between weight and the most important predictors “group” (diet group) and “time” (days when measurements were performed).
(1) Linear relationship between group and weight
Note that group is conceptually a categorical variable, the linearity of which with any variable does not make much sense. Nonetheless, the context of our data reveals each group was assigned a different type of nutritional diet. A sensible deduction these diets might differ in amount of absolute nutrition, though I have now idea about the order of contents. In this matter, it is somewhat legitimate to check the linearity between group and weight, to see if there is any notable variation of weight between groups (or different nutrition levels). Considering the guesstimate nature of this assumption, please interpret the results with caution.

According to the scatter plot above, as groups change, the weight statistics increases, with group #1 and #2 and #1 and #3 having statistically significant change. This indicates, if our assumption that different levels of nutrition existed across the groups held, we could conclude there is some linear relationships between groups (assumed to reflect different level of nutrition) and weight.
(1) Linear relationship between time(days) and weight
This is quite intuitive since both of the variables are continuous.

It is observed that over time, the weight of rats, on average, is increasing, albeit the relatively limited effect reflected by the near-to-flat slope. However, rats differed tremendously in weight when starting out at baseline (week 1).
According to the checks above I would say the assumption of linearity is somewhat met. Linear regression can be used to fit the model. My preliminary hypothesis is different types of nutrition diet will contribute differently to the weight increase of the rats, even after adjusting for the effect of different weight at baseline. I will use linear regression to fit the model, and adjust for baseline effect by adding weight at baseline as a co-variate. Please see section 1.5.1.
Next, I need to decide–do I need to consider random effect in my model and is my data appropriate for a random model. I will do it in the next section 1.4.2.
1.4.2 Check if random effect is approporiate for the data (section 1.4.2 is outside the requirement of assignment. Please go to section 2 if you’re not interested)
1.4.2.1 Graphical display of measures by individual
Another way to deal with different starting-out effect is by introducing random intercept into my model. In the context of our data, random intercepts assume that some rats are more and some less heavy in weight at baseline, resulting in different intercepts. It is also reasonable to check if rats with different baseline weight would gain weights differently (random slope). As such, it is helpful to display my data in a by-individual manner.

It is interesting to find out that rats might have a lot of variability in weight when starting out. However, some lines overlaps each other, which prevents a decisive conclusion. I will wrap the line chart into multiple graphs, one representing one rat.
#generate more explicit labels to show on each facet of graph
rats.labs <- sapply(1:16, function(x)paste("Rat #", x, sep = ""))
names(rats.labs) <- c(1:16)
#plot it
p2 <- ggplot(ratslf, aes(x = time, y = weight, group = ID, color = group)) +
geom_line(size = 1)+
geom_point()+
facet_wrap(~ID, #wrap by ID
labeller = labeller(ID = rats.labs))+ #apply the label generated
scale_x_continuous(name = "Time (days)",
breaks = seq(0, 60, 20)) + #set x scale values manually
theme(legend.position = "none",
panel.grid.major = element_blank(), #get rid of the ugly grids
panel.grid.minor = element_blank(),
panel.background = element_rect(fill = "white",#adjust the background
color = "black"),
strip.background = element_rect(color = "black",#adjust the strips aes
fill = "steelblue"),
strip.text = element_text(size =12,
color = "white"), #adjust the strip text
axis.title.x = element_text(size = 20), #adjust the x text
axis.title.y = element_text(size = 20), # adjust the y text
plot.title = element_text(size = 22, face = "bold"),#adjust the title
axis.text.x = element_text(size = 12),#adjust size of x axis text
axis.text.y = element_text(size = 12),#adjust size of y axis text
plot.caption = element_text(color = "red", size = 15))+

Now according to the graph above it is crystal clear that rats have a lot of variability in weight when starting out. For example, rats from the first and second rows of the graph started very light in weight, while rats from the third and fourth rows started heavier. This justifies an adoption of random intercept model to account for this variability. However, the general trend in weight is upward over time as we would expect and the individual rat only vary very slightly in trajectory. Following the rule of parsimony, I will adopt a random intercept only model.
1.4.2.2 Theoretical reflection of the appropriateness in adopting random intercept model
According to an outside material Data Analysis in R (https://bookdown.org/steve_midway/DAR/random-effects.html#should-i-consider-random-effects), one should consider the following question to check if random effect is necessary to consdier. They are:
(1) Can the factor(s) be viewed as a random sample from a probability distribution?
Both the individual rat and each nutrition diet used for the analysis are not population of the possible choices and could be viewed as a random sample from a probability distribution. So the answer is yes.
(2) Does the intended scope of inference extend beyond the levels of a factor included in the current analysis to the entire population of a factor?
Of course. I want to use the rats in data to extrapolate the rats out there in the world, and I want to use the types of diet to extrapolate the diets of larger number of choices(perhaps base on their trends in nutrition type or level).
(3) Are the coefficients of a given factor going to be modeled?
Yes, variable “group” is a factor and is going to be modeled.
(4)Is there a lack of statistical independence due to multiple observations from the same level within a factor over space and/or time?
Yes, I have multiple observations from the same diet group within a factor “ID” (rats) over time (days). There is a lack of statistical independence among these observations from same rats.
These done, I am confidently going to account for random effects(random intercept) for my linear model.
1.4.2.3 An alternative way to test hypothesis
My preliminary hypothesis is–different types of nutrition diet will contribute differently to the weight increase of the rats, even after adjusting for the effect of different weight at baseline. (see 1.4.1). The baseline effect will be adjusted by adding the baseline into the model formula as a predictor, so that the variability components explained by baseline could be correctly assigned to a variable recording baseline weight, and the the net variability explained by types of nutrition diet will be revealed. This is fine. However, there is still an alternative approach to test the hypothesis–by introducing random intercept into our model instead of adjusting for baseline weight. Adjustment approach assigns part of the variability to the difference in baseline; while random intercept per rat allows us to gain information about the individual rat, while recognizing the uncertainty with regard to the overall average that we were underestimating before. This is made possible by allowing each rat to be vertically shifted by their own customized amount.
2 Testing the effect of different nutrition diet on weight of rats using two approaches
2.1 Ajusting Baseline Approach
2.1.1 Removing out-liers
Outliers may have a strong influence over the fitted slope and intercept, giving a poor fit to the bulk of the data points. Outliers tend to increase the estimate of residual variance, lowering the chance of rejecting the null hypothesis. Before performing each approach, I will check and, if there is any, remove the outliers in the data.
#generate a summary data by group and ID with mean as the
#summary variable (ignoring baseline day 1)
rats.clean <- ratslf %>%
filter(time > 1) %>%
group_by(group, ID) %>%
summarise( mean=mean(weight) ) %>%
ungroup()## `summarise()` has grouped output by 'group'. You can override using the
## `.groups` argument.#check the dataset
rats.clean %>% datatable#create a function that automatically detect out-liers
is_outlier <- function(x) {
return(x < quantile(x, 0.25) - 1.5 * IQR(x) | x > quantile(x, 0.75) + 1.5 * IQR(x))
}
#clearn a new variable "out-lier" to tag outlier weight
rats.clean <- rats.clean %>%
group_by(group) %>%
mutate(outlier = ifelse(is_outlier(mean), ID, as.factor(NA))) #create outlier label#plot out-lier
rats.clean %>%
ggplot(aes(x = group, y = mean)) +
geom_boxplot() +
stat_summary(fun = "mean", geom = "point", shape=23, size=4, fill = "red") +
scale_y_continuous(name = "mean(weight), Time points 2-11")+
geom_text(aes(label = outlier), na.rm = TRUE, hjust = -0.3)
Each of the three group has one out-lier, respectively. Group 2’s mean
skewed to right, while group 3’s mean skewed to the left.
# Create a new data by filtering the outlier and draw the box plot again
rats.clean <- rats.clean %>%
filter(is.na(outlier))
rats.clean %>%
ggplot(aes(x = group, y = mean)) +
geom_boxplot() +
stat_summary(fun = "mean", geom = "point", shape=23, size=4, fill = "red") +
scale_y_continuous(name = "mean(weight), Time points 2-11")
Now the out-liers were removed. The skewness of group 2 and 3 is
minimized to some extent.
2.1.2 ANOVA to test the difference among 3 groups
rats.anova <- aov(mean ~ group, data = rats.clean)
summary(rats.anova)## Df Sum Sq Mean Sq F value Pr(>F)
## group 2 176917 88458 2836 1.69e-14 ***
## Residuals 10 312 31
## ---
## Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1The null hypothesis that there is no difference in means is rejected (p<0.001). There are some difference in the mean of weight across the rats from 3 groups. But it is still unclear which pair of group(s) have signficant difference, and post-hoc test for pairwise comparisions will be done.
tukey.test <- TukeyHSD(rats.anova)

## 3-2 85.86667 73.36717 98.36617 0From the post-hoc test results, we see that there are statistically significant differences (p < 0.0001) between each pair of groups, indicating differences between group 1 and 2, group 1 and 3 and group 2 and 3 are all significant. However, this is fine except that the different baseline is not sufficiently adjusted. Still linear regression with baseline adjusted is needed, as we discussed.
2.1.3 Linear regression with baseline adjusted

Specifically, the rats have an average weight of 221.3094 at time point 2. Changing from group 1 to group 2 would cause a rat to increase, on average, 152.72 grams in weight; while changing from group 1 to group 3 would cause a rat to increase, on average 219.62 grams in weight. Overall, the model explains 99.82 variability of rats’ weight.
2.2 Random intercept approach (section 1.5.2 is outside the requirement of assignment. Please skip this part and go to section 2 if you’re not interested)
2.2.1 Remove out-liers
#generate a variable
ratslf.clean <- ratslf %>%
group_by(group) %>%
mutate(outlier = is_outlier(weight)) %>%
ungroup
ratslf.clean <- ratslf.clean %>%
filter(outlier == F)2.2.2 Fit a random intercept model
Weight will be modeled as a function of time and group (nutrition diet type), knowing that different rats have different weights at baseline.

## group3 -0.575 0.000 0.333The fixed effects tabulated above shows that starting out, i.e. when time is day 1, the average weight, denoted by the intercept, is 244.92 grams. In addition, as a rat move from group 1 to group2, we can expect its weight to increase by about 219.52 (95% interval: 179.99 to 260.08, see table below) grams; while as a rat move from group 1 to group 3 , we can expect its weight to increase by about 262.49 (95% interval: 221.95 to 303.03, see table below) grams ; as a rat move from one day to the next, its weight is expected to increase by 0.56 (95%CI: 0.50 to 0.62) grams, indicating for the full experiment period, which lasts for 63 days, a rat is expected to have a weight gain of 35.28 grams. Note that in comparison to different groups, the effect of time change per day is way smaller, indicating the appreciable influence of different nutrition diet on weight.
The random effects tabulated above shows that weight bounces around by a standard deviation of 31.68 grams. In other words, even after making a prediction based on time and group, each rat has their own unique deviation of 31.68 grams. Note that in comparison to the different group, this effect of baseline is much smaller. For example, a rat changing from group 1 to group 3 would experience, on average, roughly 8 times more weight gain than moving from one rat to another, on average.

Inter-class correlation coefficient (ICC) is an indicator for how much group-specific information is available for a random effect to help with. It has a range of 0~1 and the closer to 1, the better.
\[ ICC=\frac{\sigma_{a}^{2} }{\sigma_{a}^{2}+\sigma^{2}} \]
In our mixed model with a random intercept, ICC is hence calculated as 1003.61/(1003.61+60.51)= 94%, which is very high and strongly suggestive that there is within-individual variability that would benefit from a random effect.
2.2.4 Display the random intercept effects
The following plot is the estimated random effects for each rat and their interval estimate. Random effects are assumed to be normally distributed with a mean of zero, shown by the horizontal line. Intervals that do not include zero are in bold. In this case, such rats are relatively higher or lower starting out compared to a typical rat. However, the number of rats with higher baseline weight (n=4) is much smaller than those with lower baseline weight (n=4), indicating the assumption is somewhat violated. In this case, random intercept model is not a robust estimator of the effect and results should be interpreted with caution.

I will further generate a density plot for the by-individual estimates of intercept. Normally, it should be normally distributed. If not, it indicates random intercept model is not a robust estimator of the effect.
#get the by-individual intercepts and pass into an object "re"
re <- ranef(rats.ri)$ID
#generate density plot
qplot(x = `(Intercept)`, geom = 'density', data = re)
The density plot is notably skewed, indicating the rats might not be a random sample of rats in nature. This will bias the estimation from random intercept model and the results should be interpreted with caution.

bprs <- read.csv("data/bprs.csv")#I prefer lower case object name for typing # convenience
#read the long format dataset
bprsl <- read.csv("data/bprsl.csv")#"l" is for long format
#delete the redundant X variable, which are the row names.
bprs <- bprs[-1]
bprsl <- bprsl[-1]1.2 Factor the categorical variables
R does not recognize categorical variables automatically as factors. I will do manually that here.

bprsf <- bprs %>% mutate(treatment = factor(treatment),
subject = factor(subject))
#for long format dataset
bprslf <- bprsl %>% mutate(treatment = factor(treatment),
subject = factor(subject)) 1.3 Check the wide format dataset
In longitudinal study, data are usually analyzed in wide format, so that variables carrying same indicators for different clusters (e.g. time points) could enter model as one parameter. To distinguish values from different clusters, another variable is generated for labeling the identity of clusters. For the reason, I will only analyze the long format dataset and check if the frame corresponds to the above-mentioned idea.

The frequency table reveals that there are 2 types of treatments, each with 180 individual measurement; there are 20 participants for each treatment, and each participant was measured 9 times (the first measurement for each participant is baseline before treatment), resulting in 360 measurements. According to the descriptive statistics for rating, the participants, irrespective of treatment and time effects, have a rating of 37.7±13.7. No missing values is present in the data.

1.4.1 Hypothesis
In the data, the variable I am interested in is “rating” (brief psychiatric rating scale). The reasons are a. it is a numeric variable and hence carries more information than factors; b. it is the only variable that varies across all the observations; c. Digging into how types of treatments would influence psychiatric tendency has substantial practical meaning in public health.
Now that I have chosen a numeric variable “rating” as the dependent variable, linear model is definitely one of the preferred choices for modeling. I will entertain two options. The first option would be to use simple linear regression. In this case BPRS rating scores will be modeled as a function of treatments and time (week) without considering the cluster level (individual-level) information. In other words, I will adopt a fixed effect model. But before a decision, I should check if there is any potential linear relationship between rating and the one of predictors “week”. This will be done in section 1.4.1.1.
A second approach to modeling this data is to model the rating as a function of treatment and time (week), while also include the cluster-level (individual-level) information. In other words, I will adopt a mixed effect model. But before a decision, I should check if participants are starting out differently and having different trajectory of rating change over this 9 weeks, and also reflect on some important assumptions for using mixed model. This will be done in section
1.4.2 Check linearity
This is quite intuitive since both of the variables are continuous.
(1) by-participant BPRS rating and week relationship

It is observed that over time, the BPRS rating of participants, on average, is decreasing. However, individual participants differed tremendously in the rating when starting out at baseline (week 0), and also differed greatly in the trajectory.
According to the checks above I would say the assumption of linearity is somewhat met. Linear regression can be used to fit the model. My preliminary hypothesis is different types of treatment will contribute differently to the BPRS rating decrease, even after adjusting for the effect of different BPRS rating at baseline. I will use linear regression to fit the model, using treatment and week as predictors. Please see section 1.5.1 (below).
Next, I need to decide–do I need to consider random effect in my model and is my data appropriate for a random model.
1.4.3 Check if random effect is approporiate for the data
(1) Graphical display of measures by individual
Another way to deal with different starting-out effect is by introducing random effect including random intercept and slope into my model. In the context of our data, random intercepts assume that some individual participants are more and some less severe in psychiatric in terms of BPRS rating at baseline, resulting in different intercepts. It is also reasonable to check if participants with different baseline BPRS rating would react differently to the different treatment (random slope). As such, it is helpful to display my data in a by-individual manner.

plot.caption = element_text(color = "red", size = 15))+
labs(title = "Fig. 1.4.3 (b) Change of BPRS rating by participants for treatment #2 in panel graph",
y = "BPRS rating")
Now according to the graph above it is clear that participants have a lot of variability in weight when starting out. For example, at baseline of week 0, participant #11 from treatment #1 has a very low BPRS rating of around 30 (see fig 1.4.3 a), while participant #11 from treatment #2 has a much higher BPRS rating of around 75 (see fig 1.4.3 b).
Additionally, although the general trend in weight is downward over time as we would expect, individual participants vary very tremendously in trajectory, for example, participant #16 from treatment #2 experienced a stable decrease of the rating over the period of 8 weeks, while participant #1 from treatment #2 underwent two big worsening and fluctuating of ratings (see fig 1.4.3 b).
(2) Theoretical reflection of the appropriateness in adopting mixed model
According to an outside material Data Analysis in R (https://bookdown.org/steve_midway/DAR/random-effects.html#should-i-consider-random-effects), one should consider the following question to check if random effect is necessary to consider. They are:
a. Can the factor(s) be viewed as a random sample from a probability distribution?
Both the individual participant and the relationship between participants’ different baseline and treatments could be viewed as a random sample from a probability distribution. So the answer is yes.
b. Does the intended scope of inference extend beyond the levels of a factor included in the current analysis to the entire population of a factor?
Of course. I want to use participant in data to extrapolate the trends of a larger population. and the two treatments in the study can be viewed as a sample of underlying treatments which is not represented in the model.
c. Are the coefficients of a given factor going to be modeled?
Yes, variable “subject” is a factor and is going to be modeled. Furthermore, it has 40 levels (20 for each treatments), which will provide considerable cluster-level information
d. Is there a lack of statistical independence due to multiple observations from the same level within a factor over space and/or time?
Yes, I have 9 observations receiving a same treatment within a factor “subject” (participant) over a period of 9 weeks. There is a lack of statistical independence among these observations.
These done, I am confidently going to account for random effects(random intercept and slope) for my linear model.
2. Fitting the model using fixed-effect and random-effect respectively
2.1 wrangling
Variable subject uses number 1 to 20 twice denoting different individual participant receiving two treatments, hence same number does not necessarily mean same participant. This might cause problem in the mixed-effect modeling since participant indexing will be included in model. I will convert it here.
bprslf <- bprslf %>%
mutate(subject = as.numeric(subject), #convert to numeric for math conversion
subject.treatment2 = subject +20) %>% #create temporary variable 21, 22...
mutate(subject.new =
case_when ((treatment == 1)~subject, #treatment 1 uses old indexing
(treatment == 2)~subject.treatment2) # treatment 2 uses new
)
bprslf <- bprslf %>%
mutate(subject = NULL, #remove old subject
subject.treatment2 = NULL, #remove tempo variable
subject = subject.new %>% factor()) #save new subject as subject, factor it
bprslf$subject #check if subject's levels grow from 20 to 40.## [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

## treatment2 -1.991083 3.135527We can see from the above summary that the participants have an average BPRS rating score of 46.45 at baseline. For every new week, they will experience an decrease of rating by 2.27 (95%CI -2.77 to -1.77) from the previous one, on average. The average influence of treatment type is very small at 0.5722, indicating participant will only have an change in rating of 0.58 on average if they moved from one treatment to another ( t = 0.44, p = 0.66). Besides, only 18% of variability is explained by the model. In other words, the finding of mixed model shows the two types of treatment do not have any influence on BPRS rating, while time has very small influence on the rating.
2.3 Random-effect model
2.3.1 Random intercept model
Herein I model the BPRS rating as a function of treatment and time, knowing (including into model the consideration) that people (subjects) have different rating baselines. Note that I do not assume treatment types and different baseline have a relationship here since I am considering random intercept here.

## treatment2 -5.885196 7.029641The fixed effect part of model summary above shows same results of coefficient with standard regression, as would be their interpretation. The standard errors, on the other hand are different here, though in the end our conclusion would be the same as far as statistical significance goes. Note specifically that the standard error for the intercept has increased. This makes sense in that with random aspects included uncertainty with regard to the overall average was more properly estimated (instead of being underestimated).
The random effect part of the summary above shows, on average, BPRS rating bounces around 9.87(95%CI: 41.74 to 51.16) as we move from one participant to another. In other words, even after making a prediction based on time point and treatment, each participant has their own unique deviation, and this deviation is almost 20 times as high as the effect of a different types of treatment, and almost 5 times as high as the effect of time (change from one week to the next).
Although the effect of treatment types is still insignificant, with random intercept model, I get more variations of participants’ ratings explained by individual difference, and this difference is even larger than the effect of time, another significant predictor (coefficient -2.27, 95%CI: -2.56 to -1.97).
2.3.1 Random intercept and slope model
Herein I model the BPRS rating as a function of treatment and time, knowing (including into model the consideration) that people (subjects) have different rating baselines (random intercept) and also that treatment types and different baseline have a correlation (randome slope).

The standard errors, on the other hand are different here, though in the end our conclusion would be the same as far as statistical significance goes.
The random effect part of the summary above shows, on average, BPRS rating bounces around 8.027(95%CI: 42.43 to 50.47) as we move from one participant to another. Note that this is a lower estimate but tighter interval than random intercept only model. The deviation for the treatment is as high as 7.58, roughly 13 times as high as the mean slope for treatment types (fixed effect). This indicates as we move from one patients to another, the effect of a different treatment could be huge, and this is an important finding since this shed some lights on why a different treatment does not show significantly different effect (it might still work on some subgroup of the patient! The future is we should identify that subgroup!)
To summarize, even after making a prediction based on time point and treatment, each participant has their own unique deviation, and this deviation is almost 16 times as high as the effect of a different types of treatment, and some of the patients might react tremendously different to the intervention with an effect of 7.58 unit change of rating as we move from one patient and treatment to another patient and treatment.
Although the effect of treatment types is still insignificant, with random intercept and slope model, I get more variations of participants’ ratings explained by individual difference at baseline and individual difference in reacting to the treatment, and these differences are even larger than the effect of time, another significant predictor (coefficient -2.27, 95%CI: -2.57 to -1.97).
